The illustrative land vehicle 100 includes a frame structure 700 (seeFIG. 7 ) and wheels 120 supported by the frame structure 700. The framestructure 700 includes, or otherwise at least partially defines, anoperator cage 132 that at least partially defines an operator cabin 134and a rear compartment 136 positioned rearward of the operator cage 132in a longitudinal direction 140 (i.e., in the lengthwise direction ofthe vehicle 100). In the illustrative embodiment, the frame structure700 includes rails 702, 704 extending in the longitudinal direction 140from respective ends 706, 708 arranged adjacent front wheels 122, 124 ofthe vehicle 100 to respective ends 710, 712 arranged adjacent rearwheels 126, 128 of the vehicle 100. However, as mentioned above, inother embodiments, the land vehicle 100 may include a monocoque. In oneexample, the monocoque may be provided in place of the frame structure700. In another example, the monocoque may be provided in addition tothe frame structure 700. In yet another example, the frame structure 700may serve as an reinforcement structure which is disposed internally inthe monocoque, and the monocoque may be disposed externally to the framestructure 700.

The illustrative wheels 120 include the front wheels 122, 124 and therear wheels 126, 128. The front wheel 122 and the rear wheel 126 areillustratively arranged on a left side 150 of the vehicle 100 (i.e.,when the vehicle 100 is viewed from the rear) and the front wheel 124and the rear wheel 128 are illustratively arranged on a right side 160of the vehicle 100 disposed opposite the left side 150. In theillustrative embodiment, the front wheels 122, 124 are positionedforward of the rear wheels 126, 128 in the longitudinal direction 140.

In the illustrative embodiment, the land vehicle 100 includes an impactmanagement system 600 (see FIG. 6 ) supported by the frame structure 700and positioned forward of the operator cage 132 in the longitudinaldirection 140. The impact management system 600 may be concealed by ahood 138 of the vehicle 100 as shown in FIG. 1 . The illustrative impactmanagement system 600 is configured to deform in response to impactforces applied thereto in use of the vehicle 100 to maintain structuralintegrity of the operator cage 132 and the rails 702, 704. Additionally,in some embodiments, deformation of the impact management system 600resulting from an impact or a crash may maintain structural integrity ofother components of the vehicle 100. In any case, as described ingreater detail below with reference to FIGS. 6 and 7 , the illustrativeimpact management system 600 includes a crash cage 610. As best seen inFIGS. 6 and 8 , the crash cage 610 extends in the longitudinal direction140 from the ends 706, 708 of the rails 702, 704 to a forward-most point170 of the vehicle 100.

It should be appreciated that the illustrative impact management system600 is configured to dissipate energy and/or forces applied to thevehicle 100 during an impact event or crash. Of course, energy and/orforces resulting from an impact event may be applied to the vehicle 100at various locations. In one example, such energy and/or forces may beapplied to the vehicle 100 at a location proximate the forward-mostpoint 170 and in a direction generally parallel to the longitudinaldirection 140 (e.g., during a head-on collision). In another example,such energy and/or forces may be applied to the vehicle 100 near one ormore of the front wheels 122, 124 and in a direction generallyperpendicular to the longitudinal direction 140 (e.g., during a sidecollision). Regardless, as a consequence of the energy dissipationeffected by the illustrative impact management system 600, lowermagnitude energy and/or forces may be transmitted to other components ofthe vehicle 100. In some cases, as discussed below with respect to FIGS.9-11 , deformation of the illustrative impact management system 600 isassociated with, or otherwise corresponds to, minimal transmission ofenergy and/or forces resulting from an impact event to the operator cage132 and the rails 702, 704 such that those components remainsubstantially intact during the impact event.

Referring now to FIGS. 2 and 3 , in the illustrative embodiment, anumber of features are included in the operator cabin 134 of the landvehicle 100. Those features are described in greater detail inco-pending U.S. application Ser. No. 17/546,555. Among other things, theillustrative operator cabin 134 includes, or otherwise houses, asteering wheel 200, an operator seat 210, and a rack 220 including trays222.

The illustrative operator cabin 134 includes a right-hand driveconfiguration 202 in which the steering wheel 200 and the operator seat210 are arranged on a right side 204 of the cabin 134. It should beappreciated that the configuration 202 may facilitate curbside deliveryfrom a driver seated in the operator seat 210 to a curbside mailbox, atleast in some embodiments. In any case, in the illustrative right-handconfiguration 202 of the operator cabin 134, the rack 220 is mounted ona left side 206 of the cabin 134 opposite the steering wheel 200 and theoperator seat 210. As such, the rack 220 occupies a space that mightotherwise be occupied by a passenger or driver seat in otherconfigurations.

The illustrative operator cabin 134 includes, or otherwise houses, apair of tracks 230, 232 that are affixed to a floor 208 of the cabin134. The tracks 230, 232 are spaced apart from one another in thelongitudinal direction 140 and arranged on the left side 206 of thecabin 134. In the illustrative embodiment, the rack 220 is movable inthe operator cabin 134 along the tracks 230, 232 in a lateral direction212 perpendicular to the longitudinal direction 140.

In the illustrative embodiment, the rack 220 is movable in the operatorcabin 134 along the tracks 230, 232 in the lateral direction 212 betweena stowed position 240 and a delivery position 300. In the stowedposition 240 of the rack 220, the rack 220 is disposed distant from theoperator seat 210. It should be appreciated that when the rack 220 isdisposed in the stowed position 240, items (e.g., mail parcels,articles, etc.) held by the trays 222 of the rack 220 may be locatedsufficiently far from the operator such that the operator may berequired to leave the seat 210 to access the items. In the deliveryposition 300 of the rack 220, the rack 220 is disposed close to theoperator seat 210. As a result, when the rack 220 is disposed in thedelivery position 300, items held by the trays 222 of the rack 220 maybe accessed by the operator without leaving the seat 210, at least insome embodiments.

It should be appreciated that in the United States, trucks are oftenclassified according to their gross vehicular weight rating (GVWR) whichmay correspond to particular truck classifications and dutyclassifications given in Table 1 below. In some embodiments, the vehicle100 has a GVWR (i.e., accounting for the weight of the truck when emptyand the payload carrying capacity of the truck when full) of between6,000 pounds and 19,800 pounds. Additionally, in some embodiments, thevehicle 100 has a GVWR of between 10,001 pounds and 14,000 pounds suchthat the vehicle 100 is embodied as, or otherwise includes, a Class 3electric delivery truck. In one particular example, in some embodiments,the vehicle 100 has a 1000 cubic foot capacity and weighs roughly 6,500pounds when empty and has a 6,000 pound payload capacity such that thevehicle 100 has a GVWR of about 12,500 pounds. Of course, it should beappreciated that in other embodiments, the vehicle 100 may be embodiedas, or otherwise include, a Class 3 vehicle, a Class 4 vehicle, or aClass 5 vehicle.

As such, the rack 220may occupy a space that might otherwise be occupied by a passenger ordriver seat in other configurations. Furthermore, in such a left-handdrive configuration, the tracks 230, 232 may be arranged on the rightside 204 of the cabin 134.

In some embodiments, the vehicle 100 is embodied as, or otherwiseincludes, any one of a Class 3 through Class 5 electric delivery truckhaving a right-hand drive configuration. Additionally, in someembodiments, the vehicle 100 is embodied as, or otherwise includes, anyone of a Class 3 through Class 5 electric delivery truck having aleft-hand drive configuration. Further, in some embodiments still, thevehicle 100 is embodied as, or otherwise includes, any one of a Class 3through Class 5 electric delivery truck having another suitable driveconfiguration, such as a configuration in which the steering wheel 200and the operator seat 210 are centrally located in the cabin 134 in thelateral direction 212, for example.

Referring now to FIG. 4 , in the illustrative embodiment, the landvehicle 100 includes electric motors 400 configured to producerotational power to drive rotation of the wheels 120 in use of thevehicle 100. Each of the electric motors 400 is directly integrated intoone of the wheels 120 such that the vehicle 100 includes four electricmotors 400. As shown in FIG. 4 , one of the electric motors 400 (i.e.,the electric motor 402) is directly integrated into the wheel 124.

The illustrative motor 402 is embodied as, or otherwise includes, anydevice that is capable of being driven by electrical energy supplied bya power cell assembly 810 (see FIG. 8 ) to produce rotational power. Asindicated above, the illustrative motor 402 is directly integrated intothe wheel 124 so that rotational power produced by the motor 402 isprovided directly to the wheel 124 in use of the vehicle 100. At leastin some embodiments, the motor 402 is directly integrated into the wheel124 such that the motor 402 and the wheel 124 are concentrically mountedabout an axis 404. In such embodiments, the axis 404 may define, orotherwise coincide with, a rotational axis of the wheel 124.

In some embodiments, each of the electric motors 400 is configured togenerate about 100 horsepower (hp) in use of the land vehicle 100. Insome embodiments, each of the motors 400 may be embodied as, orotherwise include, a brushed DC motor, a brushless DC motor, a switchedreluctance motor, a universal AC/DC motor, an induction motor, a torquemotor, a synchronous motor, a doubly-fed electric machine, an ironlessor coreless rotor motor, a pancake or axial rotor motor, a servo motor,a stepper motor, a linear motor, or the like. Of course, it should beappreciated that in other embodiments, each of the motors 400 may beembodied as, or otherwise include, another suitable device capable ofconverting electrical energy supplied by the power cell assembly 810 torotational power to drive the wheels 120. In some embodiments, each ofthe electric motors 400 is configured to generate a sufficient amount ofrotational power and/or motive force to drive movement of one or more ofthe wheels 120 over an estimated service life of the vehicle 100, whichmay encompass a significant number of missions and/or delivery trips. Insuch embodiments, each of the motors 400 may be configured to generateless than 100 horsepower in use of the vehicle 100 or greater than 100horsepower in use of the vehicle 100, whatever the case may be.

In the illustrative embodiment, each of the electric motors 400 iscoupled to one of the wheels 120 without any transmission gearinginterposed therebetween. Even more, at least in some embodiments, theillustrative land vehicle 100 entirely omits one or more transmissions.Consequently, in such embodiments, the land vehicle 100 is free fromcomponents that may be present in conventional transmissions, such astorque converters, rotating torque-transmitting mechanisms or clutches,stationary torque-transmitting mechanisms or brakes, transmissiongearing, pressure control valves, shift control valves, regulatorvalves, check valves, and various components of electro-hydrauliccontrol systems. As a result, the powertrain and/or drivetrain of thevehicle 100 may include significantly fewer parts than otherconfigurations, thereby facilitating maintenance, reliability, andreduced design complexity, among other things.

In the illustrative embodiment, the electric motors 400 of the landvehicle 100 are the only components of the vehicle 100 capable ofgenerating rotational power to drive the wheels 120. The illustrativeland vehicle 100 therefore does not include an internal combustionengine. As such, the land vehicle 100 is free from a number ofcomponents that may be utilized in conventional configurations totransmit rotational power from one or more internal combustion enginesto one or more wheels, such as driveshafts, differentials, and axles,just to name a few. In that additional respect, the powertrain and/ordrivetrain of the vehicle 100 may include significantly fewer parts thanother configurations, which may facilitate maintenance, reliability, andreduced design complexity as mentioned above.

Referring now to FIG. 5 , in the illustrative embodiment, the landvehicle 100 includes brake systems 500 configured to resist rotation ofthe wheels 120 to stop and/or slow the vehicle 100 in use thereof.

Each illustrative brake system 500 includes a disc 502, a brakingdevice 510, a braking device 530, and a braking device 550. Theillustrative disc 502 includes notches 504 defined betweencircumferentially adjacent teeth 506 of the disc 502. The illustrativebraking device 510 is configured to contact an outer face 508 of thedisc 502 to resist rotation of one of the wheels 120 in use of thevehicle 100. The illustrative braking device 530 is circumferentiallyspaced from the braking device 510 about the disc 502 and configured tocontact the outer face 508 thereof to resist rotation of one of thewheels 120 in use of the vehicle 100. The illustrative braking device550 is configured to contact one or more teeth 506 of the disc 502 toresist rotation of one of the wheels 120 in use of the vehicle 100. Itshould be appreciated that any one of the braking devices 510, 530, 550of each brake system 500 may be activated to resist rotation of one ofthe wheels 120 in use of the vehicle 100 and thereby provide redundantbraking means. Additionally, it should be appreciated that the multiplebraking devices 510, 530, 550 may be activated in combination with oneanother to cooperatively resist rotation of one of the wheels 120 in useof the vehicle 100.

In the illustrative embodiment, the disc or rotor 502 of each brakesystem 500 is configured for rotation about a rotational axis 503. Theillustrative disc 502 is coupled to the wheel 120 for common rotationtherewith about the axis 503, at least in some embodiments.Additionally, in some embodiments, the disc 502 may be integrally formedwith the wheel 120. At an inner diameter 505 thereof, the disc 502 isformed to include the notches 504 that are defined betweencircumferentially adjacent teeth 506 of the disc 502.

In the illustrative embodiment,the braking device 510 includes only one caliper 512. Furthermore, inthe illustrative embodiment, the braking device 510 includes six pistons(only pistons 516, 518, 520 are shown in FIG. 5 ) that are at leastpartially housed by the only one caliper 512. However, in otherembodiments, it should be appreciated that the braking device 510 mayinclude only one piston. The illustrative braking device 510 alsoincludes a pair of brake pads (only brake pad 524 is shown) that areconfigured to contact opposite sides (i.e., outer and inner sides) ofthe disc 502 to resist rotation of the wheel 120 about the axis 503 inuse of the vehicle 100.

The caliper 512 of the braking device 510 may have a variety ofconstructions. In the illustrative example, the caliper 512 has atwo-piece construction in which two parts (only part 526 is shown inFIG. 5 ) are secured to one another in close proximity to an end 528 ofthe caliper 512 by fasteners 527. In the illustrative example, the partsof the caliper 512 are spaced apart from one another in close proximityto an end 529 that is arranged opposite the end 528. The brake pads arecoupled to inner sides of the parts and arranged in confronting relationwith one another to permit contact between the brake pads and the disc502 when the disc 502 is positioned between the pads adjacent the end529. In the illustrative example, a sensor 580 is coupled to the part526 of the caliper 512 at an outer periphery thereof. The sensor 580 isconfigured to provide a signal indicative of wear or degradation of thebrake pads in use of the vehicle 100, at least in some embodiments. Inother examples, however, the caliper 512 may have another suitableconstruction and be formed from another suitable number of parts.

The illustrative braking sensor 562 is configured to provide asignal to a control system (not shown) indicative of a rotational speedof the wheel 120 in use of the vehicle 100, at least in someembodiments. The signal provided by the braking sensor 562 may beutilized to control one or more components of an anti-lock brake system(not shown) included in the vehicle 100.

In some embodiments, fluid connections 564 are located radially betweenthe rotational axis 503 and the inner diameter 505 of the disc 502. Thefluid connections 564 may be utilized to circulate cooling fluiddelivered from a cooling fluid source (not shown) through the wheel 120to cool the wheel 120 in use of the vehicle 100, at least in someembodiments. Each of the fluid connections 564 may be embodied as, orotherwise include, a projection 566 that extends outwardly away from aninterior 568 of the wheel 120 and parallel to the rotational axis 503such that the fluid connections 564 are not generally not recessed. Insome embodiments, a connector 570 is located in the interior 568 of thewheel 120 adjacent the fluid connections 564. The connector 570 may beconfigured to interface with a single low voltage cable 572 that is atleast partially positioned in the interior 568.

In the illustrative embodiment, the braking device 530 is an electronicparking brake mechanism. Additionally, in the illustrative embodiment,the braking device 550 is a parking pawl mechanism. It should beappreciated that in use of the vehicle 100, the braking devices 530, 550may be operated by a control system independently of one another and/orin concert with one another.

As mentioned above, the illustrative electronic parking brake mechanism530 is configured to contact the outer face 508 of the disc 502 toresist rotation of the wheel 120 about the axis 503 in use of thevehicle 100. As best seen in FIG. 5 , the parking brake mechanism 530 iscircumferentially spaced from the braking device 510 about the disc 502and the axis 503. More specifically, the parking brake mechanism 530 andthe braking device 510 are circumferentially spaced about 180 degreesfrom one another about the disc 502 and the axis 503. In theillustrative arrangement, among other components, the fluid connections564 and the connector 570 are circumferentially located between theparking brake mechanism 530 and the braking device 510.

At least in some embodiments, the illustrative parking brake mechanism530 includes a number of features similar to corresponding features ofthe braking device 510. In such embodiments, the parking brake mechanism530 includes a housing 532, one or more actuators or pistons 538 atleast partially housed by the housing 532, and brake pads (only brake540 is shown) supported by the housing 532 that are configured tocontact opposite sides (i.e., outer and inner sides) of the disc 502 toresist rotation of the wheel 120 about the axis 503 in use of thevehicle 100. In addition, the parking brake mechanism 530 may include anumber of components not depicted in the Figures, such as one or moreseals, dust boots, bleeder devices, anti-rattle clips, brake shoes,linings, locating pins, mounting pins, bearings, retainers, caps, anchorplates, mounting plates, spindles, or the like.

In the illustrative example, the housing 532 has atwo-piece construction in which two parts (only part 534 is shown) aresecured to one another in close proximity to an end 536 of the housing532. In the illustrative example, the parts of the housing 532 arespaced apart from one another in close proximity to an end 537 that isarranged opposite the end 536. The brake pads are coupled to inner sidesof the parts and arranged in confronting relation with one another topermit contact between the brake pads and the disc 502 when the disc 502is positioned between the pads adjacent the end 537. In the illustrativeexample, a sensor 542 is coupled to the part 534 of the housing 532 atan outer periphery thereof. The sensor 542 is configured to provide asignal indicative of wear or degradation of the brake pads in use of thevehicle 100, at least in some embodiments. In other examples, however,the housing 532 may have another suitable construction and be formedfrom another suitable number of parts.

As mentioned above, the illustrative parking pawl mechanism 550 isconfigured to contact one or more teeth 506 of the disc 502 to resistrotation of the wheel 120 in use of the vehicle 100. Unlike someconventional devices, the illustrative parking pawl mechanism 550 is notfitted to, and does not interact with, a transmission of the vehicle100, since the vehicle 100 omits one or more transmissions as indicatedabove. Thus, unlike some conventional devices, the illustrative parkingpawl mechanism 550 does not lock an output shaft of a transmission toprevent rotation of the wheel 120.

In the illustrative embodiment, the parking pawl mechanism 550 includesa pawl or pin 552 at least partially housed by a housing 556. The pawl552 may be sized to contact one or more of the teeth 506 in use of themechanism 550.

The one or more actuators 554 are configuredto drive movement (e.g., extension) of the pawl 552 relative to thehousing 556 to contact one or more of the teeth 506 and thereby resistrotation of the wheel 120, at least in some embodiments. Additionally,in such embodiments, the one or more actuators 554 are configured todrive movement (i.e., retraction) of the pawl 552 relative to thehousing 556 to release the pawl 552 and thereby permit rotation of thewheel 120.
